A skier is pulled up a slope at a fix velocity by a tow bar. The slope is inclined at 25.0 degree with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier mass is 55.0 kilogram, and the coefficient of kinetic friction between the snow and the skis is 0.120. Obtain the magnitude of force that the tow bar exerts on the skier.
